How to write GIF image files in Java with JDeli

In this article, I will cover how to write out images as Gif images in Java. We also have a related article covering how to read GIF files in Java.

JDeli provides support for GIF along with lots of other image formats.

How to write an image as a GIF file with JDeli

1. Add JDeli to your class or module path. (download the trial jar).
2. Create a File (or OutputStream) object

   File file = new File("/path/to/outputFile.gif"));

3. Pass image, Heic type, and File (or OutputStream) object into write method

   JDeli.write(bufferedImage, "gif", file);

In JDeli you can also use a typesafe version

JDeli.write(bufferedImage, OutputFormat.GIF, file);

or pass in a object for more control over GIF image output, such as level of Compression.

GifEncoderOptions options = new GifEncoderOptions();
JDeli.write(bufferedImage, options, file);

Why do developers choose JDeli over free alternatives?

1. Works with newer image formats such as AVIF, HEIC, JPEG XL, WEBP (AVIF next release) that are not supported in Java.
2. Better support than alternatives for JPEG, PNG, TIFF.
3. Process images up to 3x faster than ImageIO and other Java image libraries.
4. Prevent JVM crashes caused by native code in other image libraries such as ImageIO.
5. Image security as JDeli processes images on your servers with no calls to any external system or third party library.

// Read an image
BufferedImage bufferedImage = JDeli.read(dicomImageFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(heicImageFile);

// Write an image
JDeli.write(bufferedImage, "heic", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpegImageFile);

// Write an image
JDeli.write(bufferedImage, "jpeg", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(jpeg2000ImageFile);

// Write an image
JDeli.write(bufferedImage, "jpx", outputStreamOrFile);

// Write an image
JDeli.write(bufferedImage, "pdf", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(pngImageFile);

// Write an image
JDeli.write(bufferedImage, "png", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(tiffImageFile);

// Write an image
JDeli.write(bufferedImage, "tiff", outputStreamOrFile);

// Read an image
BufferedImage bufferedImage = JDeli.read(webpImageFile);

// Write an image
JDeli.write(bufferedImage, "webp", outputStreamOrFile);
